Place Parts

Adding a resistor

1)Clickhotkey p to place a part

2)Select part Rfrom the Analog library

3)click <OK> to close thewindow

4)clickhotkey r to rotate the part

5)click <esc> to stop placing the part

Adding a BJT

6)Clickhotkey p to place part

7)Select part Q2N2222 from the Bipolarlibrary

8)click <OK> to close thewindow

9)left click with your mouse to position the BJT in your schematic window

10)click <esc> to stop placing the part

11)Create the intermediate schematic shown below by addingTWO Vsrc parts from the library source.

Note parts can be repositioned by dragging them. See table on right for helpful shortcut keys

Connecting Parts

After placing the parts you may wish to connect them using wires (also called nets).

12)Use hotkey w OR select the Place wire icon from the toolbar on the r.h.s. of the screen (see below)

a)Click your mouse at the starting position of your wire

b)Move (do not drag) your mouse to the location where you want a bend. Click your mouse. This will create a bend (you may repeat this step for multiple bends)

c)Move (do not drag) your mouse to the end location and click again.

d)Click <esc> key to stop drawing wires.

13)Draw wires as shown below

14)Naming wires: It is much easier to maintain a design if you name the wires (nets) on your diagram.

a)From the tool bar on the rhs(see below) clickthe place net aliasicon, OR from the top toolbar: Place->net alias

b)Type the name of the net in the menu that follows

c)With your mouse select the net that you wish to name

d)Click <esc> to end the place net alias command

Note wires that have the same name are considered to be connected. You can use this feature to create less cluttered more readable schematics.

e)Name the wires on your schematic as shown

To simulate a schematic you must have a ground. Ground can be defined by using a ground part or by naming nets with the number ZERO

Modifying Properties

15)Double click the value of the resistor (1K) and change it to be 2.5K, click <OK> to close the window.

16)Double click the DC value of the voltage source (DC=) and change it to be 5, click<OK> to close the window.

Your schematic is now complete

17)Save your schematic - ---From the main menu: File->Save
